The problem is that it's not bringing in flush water. It will pump dry
without a problem.

I got that from your first post. But a blockage in the intake isn't the
only thing that can cause various makes/models of manual toilet to stop
bringing in flush water..which is why I asked you more information. So
one more time: what's the make/model/age of your toilet? Does the pump
feel any different--looser, just can't prime...or backpressure--than it
did when it worked? And one more question: Do you layup for winter and
did this just start happening when you used the boat again this spring?
Or do you use the boat year-round?

If I have enough info, I can prob'ly point you toward the cause of the
problem without having to type every possible reason that can cause
every make/model manual toilet to stop bringing in flush water.
